Note:

With power supply units with integrated HART resistance (internal

resistance approx. 250 Ω), an additional external resistance is not

necessary. This applies, e.g. to the VEGA instruments VEGATRENN

149A, VEGAMET 381, VEGAMET 391. Common Ex separators are

also usually equipped with a sufficient current limitation resistance. In
